in my opinion S2 is a waste of money...i have less what S2 cost and i would murder a S2 car. unless u really wanna go mopar and not have ur car tuned then go for it but there no way i would spend that kind of money to get that amount of power. look at how much S2 costs-890 bucks

get the DP and exhaust
get the FMIC
get the hard pipes with a BOV
get the SRI

now u got 890 bucks left...
find a used AFC2...it'll run u 150-200
20-22psi on a AGP WGA-150
AGP return line kit-380 bucks
labor tuning for the AFC will be about 250

ok its about 100 bucks more than S2 but instead of 265hp and 280tq u will be minum 290whp and 350wtq. but that is if u wanna go through the trouble of having ur car tuned...if u dont want to deal with ur car just go S2
